Add DNS record

Last update: October 05 2026Open in Markdown

If a network is attached to the zone, A or AAAA records in the zone are added automatically when a port is created in the network. Such records are labeled with the Auto tag. A or AAAA records can also be added manually. CNAME, MX, and TXT records can only be added manually.

Only one record of each type can exist for a domain name. If you do not yet have a resource record of the required type for the domain name, add a record. If you already have a record of the required type for the domain name, add a value to it.

If a network is attached to the zone and you manually added an A or AAAA record for the domain name, and then created a port with that domain name, the port's IP address will be automatically added to this record as an additional value. The Auto tag will be added to the record, and it will start updating automatically when the port data changes.

You can check if a network is attached to the zone in the Control panel: in the top menu, click Products → Cloud Servers → Private DNS → the DNS resolvers tab → the network row → the DNS zone field.
